Solve y-2x-3=0

$$y - 2 x - 3 = 0$$

Solve for x

$$x=\frac{y-3}{2}$$

Steps for Solving Linear Equation

Subtract y from both sides. Anything subtracted from zero gives its negation.

$$-2x-3=-y$$

Add 3 to both sides.

$$-2x=-y+3$$

The equation is in standard form.

$$-2x=3-y$$

Divide both sides by -2.

$$\frac{-2x}{-2}=\frac{3-y}{-2}$$

Dividing by -2 undoes the multiplication by -2.

$$x=\frac{3-y}{-2}$$

Divide -y+3 by -2.

$$x=\frac{y-3}{2}$$

Solve for y

$$y=2x+3$$

Solution Steps

Add 2x to both sides. Anything plus zero gives itself.

$$y-3=2x$$

Add 3 to both sides.

$$y=2x+3$$
